Acer Aspire 7535 BIOS Not Booting

Hello all,
I have an Acer Aspire 7535-5415 that doesn't boot up.
The laptop belongs to a friend of mine and basically her daughter said that she got some sort of an error message, she rebooted the laptop and that was the end of it. I could not get more details from her (the daughter is 8 yrs old)

I checked the hard drive and the RAM and all seems to be seated properly.
basically when the laptop is powered on, the screen remains blank (no dim image or light or anything), the fan comes on for few seconds then goes off, the DVD drive blinks for few seconds then nothing.

I searched the threads and tried to do the BIOS recovery.
I created a bootable USB stick, copied Phlash16.exe along with the proper bios file from Acer (2.04)and modified the autoexec.bat with the following line:

phlash16.exe /x /c /mode=3 /BU /bbl JV70_204.WPH

i pulled the battery and the hard drive out of the laptop and tried booting the recovery drive with all the key combinations that i could find online (Fn+B also tried Fn+Esc) to no available.
the USB that i use is a 256Meg no brand type and it has no LED on it, so i cannot see if the laptop is reading it or not. i plugged a 1Gig stick that has an LED and it gets power, but no read/write activity.

I am not sure what else to try, any ideas would be greatly appreciated. the laptop is out of warranty.

Thanks in advance.

 

You need to use WinCris to create a crisis disk - a simple DOS boot disk won't work.

Also, some laptops require a USB floppy drive for this - a flash drive will not always work.

 

thanks for the Reply NetRoller, i'll give that a shot, i didn't create a floppy becasue the WPH file is over 2 Megs in size, but i noticed that WinCris has the compress the file option.
I have WinCris version 1.0.0.4, would this work, or do i need a newer version if exists?
-----------------
I created a crisis disk and used a USB floppy disk to boot the laptop, there is no activity at all in the floppy, so t he laptop is not even attempting to read it. i pulled the battery and the hard drive out. is there anything i am missing?
any key combinations?

 

Usually it's Fn+Esc on Acers. You have to press and hold Fn+Esc while plugging in the power adapter, and continue holding it while pressing the power button.

 

Yes, this is what I tried. I also tried Fn+B and WinKey+B. I think the laptop might have a bigger problem than just a bad BIOS.

I tried every crusis method but nothing,,
Sorry for my english..
